2 Corinthians 7
9 Ref I now rejoice, not that ye were made sorry, but that ye were made sorry unto repentance; for ye were made sorry after a godly sort, that ye might suffer loss by us in nothing.
10 Ref For godly sorrow worketh repentance unto salvation, `a repentance' which bringeth no regret: but the sorrow of the world worketh death.
